Breasts should not be kneaded hard, mainly because the tissues and blood vessels in the breast area are relatively fragile. Breasts are a fragile tissue, and the soft tissues contained in them are sensitive, so kneading them hard will lead to external damage to the breast tissue, which can lead to inflammatory diseases, and may cause mastitis and breast atrophy. If you repeatedly stimulate the breasts, it will lead to prolonged congestion of the breasts, which is not good for the health of the breasts. Appropriate massage can promote the local blood circulation of the breasts, and it is good for the breasts, but if you rub it hard it will have an effect on the localization. Therefore, patients should not often knead the breast with force in daily life, and do not let the localization be squeezed.
